|Wetland Restoration Maps
Two types of maps were produced by the Merrimack River Watershed Wetland Restoration GIS model:
1. Site Location Maps, USGS Base
Forty-three (43) maps based on the USGS 7.5-minute topographic quadrangles, showing the location of 951 potential wetland restoration sites in the watershed. Note that there are 48 quadrangles in the watershed, but only 43 have Candidate Sites. The index map below shows the location of each of these quadrangles in relation to watershed and town boundaries. By clicking on the map below, a PDF file will open of the corresponding quadrangle. The PDFs are LARGE FILES (4-5 MB), it is recommended that you save the files to your computer before viewing.
2. Priority Site Plans
Thirty (30) high priority sites were selected for field study and subsequent development of conceptual restoration plans. An existing condition plan and a conceptual restoration plan were created for each of these sites. By clicking on a site in the index map below (red areas and labels), you will be brought to a pdf of the corresponding site plans. The PDFs are LARGE FILES (400 KB - 1 MB), it is recommended that you save the files to your computer before viewing.
It is very important to understand that, due to the limitations of GIS, the model cannot identify or assess all potential restoration opportunities. While the results suggest that there are numerous opportunities throughout the watershed, and that the model does a good job of identifying those opportunities, it is also clear that local Conservation Commissions and other local and regional organizations may know of other viable wetland restoration sites that are not included in this study and which do not appear on these maps. The exclusion of these sites should not be taken as evidence that such a site would not qualify for an ARM grant or other funding sources.
